Urgent help,

Unity Engine

Hello everyone
I’m kinda having a trouble with making an enemy stopping at certain distance with this script the game is 2D game

and here’s the script I have for enemy (following) purpose

using UnityEngine;
using System.Collections;

public class FacePlayer : MonoBehaviour {

    public float rotSpeed = 180f;

    public Transform player;

    void Update () {
    if (player == null)
        {
        GameObject go = GameObject.Find ("Player");

            if (go != null){
                player = go.transform;
            }
        }

        if (player == null)
            return;

        Vector3 dir = player.position - transform.position;
        dir.Normalize ();

        float zAngle = Mathf.Atan2 (dir.y, dir.x) * Mathf.Rad2Deg - 90;

        Quaternion desiredRot = Quaternion.Euler (0, 0, zAngle);

        transform.rotation = Quaternion.RotateTowards (transform.rotation, desiredRot, rotSpeed * Time.deltaTime);
    }
}

So what am I missing? I tried in update function tried this

        if (Vector3.Distance (transform.position, Player.position) > maxDistance)

and I added the maxDistance value but the enemy starts moving forward and keeps going forward for some reason.

Thanks in advance!

Urgent help??? I thought you were trapped in a lift or something… Seriously choose a better title…

Anyways, for your non urgent problem, where is the code that moves the enemy? The Update method above rotates the enemy but I cant see any movement code? Your if statement is fine, have you tried Debug.log on both transforms, the enemy and player, to see if they are what you expect.

lol, well I am trapped in this code, and also another problem but I’m not gonna bother asking about it it’s not easy to fix however thanks a ton for your quick response, here’s the movement script

using UnityEngine;
using System.Collections;

public class EnemyMovement : MonoBehaviour {
   
    public float maxSpeed = 2f;
   
    void Update ()
    {

        Vector3 pos = transform.position;
       
        Vector3 velocity = new Vector3 (0, maxSpeed * Time.deltaTime, 0);
       
        pos += transform.rotation * velocity;
       
        transform.position = pos;
    }
}

Thanks a ton!

regards.

Ok so add your if statement around all the code in the update method of that script.
